Model 5154
Video Generator/Audio De-Embedder Module
Note: It’s possible that during the update
process any LEDs located on the USB flash
drive may light steadily or flash with vary-
ing patterns. These actions are not signifi-
cant to the Model 5154’s firmware update
process. (The status LEDs on various USB
flash drives seem to behave in different
ways so there are no universal patterns
that can be identified.)
Identifying the Installed
Firmware Versions
As previously discussed in the Configura-
tion section of this guide, a file is automati-
cally written to a USB flash drive whenever
it is plugged into the Model 5154. This file,
named STATUS.TXT, provides details of the
Model 5154’s firmware (embedded soft-
ware), hardware, and configuration param-
eters. These parameters include the version
numbers of the MCU and FPGA firmware
that are stored in the module. This informa-
tion is also available when using a Model
5190 Remote Access Module with the
Model 5154. A third method is also avail-
able to determine the two firmware version
numbers. The Model 5154’s status LEDs
are used during the power-up sequence to
display the numbers in a cryptic but effec-
tive manner. While the display method is a
bit unique, once a user gets accustomed to
what’s actually happening during power up
it should be fairly straightforward to “read”
the version numbers.
To identify the installed firmware versions:
1. Power up the Model 5154. The LEDs
will perform a “walk-through” test, with
each LED briefly lighting in a sequence.
2. Next the Power LED will light and
remain lit.
3. Very shortly after the Power LED lights
the USB Activity LED will light to in-
dicate that the MCU firmware version
is being displayed by the eight Digital
Audio Inputs Signal Present LEDs. The
top row of four LEDs will display the
major version number with a range of
1-4. The bottom row of four LEDs will
display the minor version number with
a range of 0 (no LED lit) to 4. Refer to
Figure 9 for details.

firmware versions. In this example, the version shown is 2.3.
